It is expected proposals to be dominated by witnesses. Most developers here are witnesses.
It is also not unexpected witnesses leading curation groups, people who tend to be go getters and builders tend to be witnesses as well.
Trending, I can’t speak for that as voting has always been fickle and showing favoritism.
I am not surprised by any of these especially while we don’t have a massive userbase fighting over the reward and attention pool.
Hive is barely a month old there and is a ton of potential. It is already performing better than Steem in almost every metric except centralization, censorship, and freezing accounts.
